Tunisia's new unity government takes office

A new Tunisian unity government took office Monday in the birthplace of the Arab Spring, with Prime Minister Youssef Chahed, the country’s youngest-ever leader, facing major economic and security challenges. Chahed, who turns 41 next month, becomes the former French colony’s seventh prime minister in less than six years, following a 2011 revolution that ousted strongman Zine El Abidine Ben Ali. It formally took office at a ceremony in Carthage just outside Tunis during which outgoing premier Habib Essid, 67, handed over power.
